"Medusa," a deadly virus becomes a worldwide epidemic. In order to escape from this deadly virus, a handful of people are chosen to be put into a cold sleep, laying in a capsule hoping for the future cure. Kasumi, a teenage girl is one of the 160 chosen for this procedure, and is guided to a Cold Sleep Capsule Center (CSCC) inside an ancient castle. Understanding that it is hardly possible, Kasumi goes to sleep still anticipating for a reunion with her twin sister Shizuku, who also is infected with the virus. As Kasumi and the others awake, they notice that the CSCC is not as they remembered. Just like the story of "Sleeping Beauty," the castle is covered with thorn, and the awaken are attacked by unknown creatures and monsters! How long were they asleep? Where did the monsters come from? What has happened to the world?

Abandoned in the midst of an enigma, the escapade of the seven survivors begins...

When watching the trailer for this anime film I had big expectations about what I was going to see. Here you have a sci-fi/thriller with killer virus threatening society, survivors trying to stay alive and mysterious monsters inhabiting the area of the last set of people. It sounds good doesn't it?

The first part of the film feels ...

Every now and then a manga well deserving of praise is adapted into a fairly mediocre anime; unfortunately King of Thorn is one of those adaptations.

The source material is six volumes long; a fine length to adapt into a film, and for the most part the pacing is handled with care. King of Thorn sees a colourful cast of cryogenically frozen characters awaken to a future ravaged by monsters. The introduction is well executed; it grabs your attention and gets you wondering. As the film progresses, it becomes rather typical of the survival horror genre, but the film exhibits a certain freshness as it isn't ...

This is an absolute abomination of the author's original work. Wow . . . I mean, just, wow. Don't get me wrong, my rating has nothing to do with the animation, or even the plot, since it is a good plot, but it's just NOT "King of Thorn." They should have either done A) justice to the original manga or B) made a totally different movie with different characters. Don't ravage such a fantastic story as "King of Thorn," just don't DO it!
